In the Linux kernel, the following vulnerability has been resolved:
wifi: ath9k: don't allow to overwrite ENDPOINT0 attributes
A bad USB device is able to construct a service connection response message with target endpoint being ENDPOINT0 which is reserved for HTCCTRLRSVD_SVC and should not be modified to be used for any other services.
Reject such service connection responses.
Found by Linux Verification Center (linuxtesting.org) with Syzkaller.
